IMPROVEMENT IN LUBRIUATORS EOR AXLES, AND MODE OF ATTAGHING THEM "TO AXLES...

. TO ALL WHOM IT MAY CONCERN:

Be it known that I, LEVI ADAMS, of Amherst, in the county of Hampshire, and State of Massachusetts, have invented a new and improved Method ofrAttaching Hubs to Axles; and Ido herebydeclare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of, this specification.

This inventionrela-tes to-a. new and improved manner of attaching hubs to axles, and isfdesigned as an improvement on the old mail-axle, and all others which are provided with means for securing the hub on the arm, at the inner end of the former.

The .object of my invention is to obtain a goed bearingrfor theV hub on the arm, iectually prevent the escape of lubricating-material from the arm, prevent the advent of dust between the box and arm, and admit of 'the wheel being readily attached to and detached from its axle. In the accompanying sheet ofd'rawin'gs.

Figure 1 is a longitudinal central section of my invention; taken in the line :c zr, fig. 2. l

Figure 2, an inner end view of the same.

Similar letters of reference indicate corresponding parts. i i

' A represents a portion of the axle of a vehicle, and B one of the arms thereof. These parts may be o f l usual construction, and therefore do not require la minutedescription. The arm B is provided with a collar, G, n at its inner end, or junction with the axle, said collar having n. V-shaped periphery, as shown in iig. 1. D representsthe box, which is closed at its outer end, and is secured in the hub'so as to turn with it. This box extendsV beyond the inner end of the hub, and is provided with a flange, a, at its inner end, which iange extends all l i around the box. E E represent two semicircular jaws, Vprovided at one end with lugs or projections,l b b, con-4 nected together b'y a pintle, c, to form a hinge orjoint, by which the jawsV are permitted to open an-d close, said pintle being connected with a clip, F, on the axle. These jaws E E are grooved 'at their inner surfaccs, to i receive, when closed, the iiange a, at the inner end of the box D, and a V-shaped groove is also made in the n inner surfaces of the jaws, to receive the periphery of` the` collar Cron the arm, (see iig. 1.) The jaws E Ea're secured in a closed state by means of a button, the same consisting of a metal plate, d, attached to a rod, e, the lowerend of which is pivoted in a lug, f, on the lower jaw, a corresponding lug, f', on the 'upper Ajaw being slotted, to allow the rod e to pass into it, and the plate el to iit over the upper surface ofthe lug f', said plato d being screwed firmly down on the upper surface of the lug f by a screw-nut, y, on'thcupper end of rod e. l It will be seen from the above description that, by the itting of the 'jaws E E over the collar C, the'jaws are firmly connected to the axle, and by having the jaws fitted over the ilange a, the hub will be secured on the arm. The upper jaw E is provided at its top with a cup, FX, which communicates with theV groove in the inner surface of said jaw. This oil-cup has a lid, h, in order to exclude dust, and the inner side of thc jaws E, that is, the E Aside opp'osite the inner end of the hub, has packing, z', attached, which, when thejaws E E are closed, tits snugly around the box D, and prevents the escape of oil from within the jaws, and also prevents the advent of dust therein. l v

This improvement admits of the very ready attachment of the wheel' to the axle, and its detachmenttherefrom,and is a great improvement over the old and well-known mail-axle, in which the liub is secured n the axle by means oi" bolts passing longitudinally through the entire lengthof the hub, and through a plate or disk, which bears against a collar on the axle. v

Il claim as new, and desire to secure by Letters Patenti 1. The two jaws E E, fitted or secured to the axle, as shown, in combination with the collar C, at the inner end of the arm B, and the flange a, at the inner end of the box D, all being constructed and arranged substantially in the manner as and for the purpose set forth.

.2. The packing z' and the oil-cup F, in combination with the jaws EEthe collar C on the axle,an`dV the flange a on the box D, all arranged substantially as and for the purpose specified.

3. The button, consisting of metal plate d, rod e, pivoted in lugf, and the nut g, when used in combination with the' jaws vE'E, and all arranged substantially in the manner as and for the purpose set forth.
